Abstract

Linvention concerne des dispositifs et des techniques qui comprennent une combinaison de forces et deffets électrocinétiques, diélectrophorétiques, électrophorétiques et fluidiques pour séparer des cellules, des nanovésicules, des nanoparticules et des biomarqueurs (ADN, ARN, anticorps, protéines) dans des tampons et des échantillons biologiques de force conductrice (ionique) élevée. Selon les modes de réalisation décrits, une combinaison de forces diélectrophorétiques continues et/ou pulsées (DEP), de forces électrophorétiques CC continues et/ou en champ pulsé, de microélectrophorèse et dune fluidique contrôlée est utilisée avec des réseaux délectrodes. Lutilisation de dispositifs DEP à chambre et dun dispositif à réseau délectrodes relativement plus grand et correctement dimensionné qui associe des forces fluidiques, électrophorétiques et DEP permet notamment danalyser de manière plus directe, rapide et efficace des volumes à la fois plus grands et/ou cliniquement pertinents de sang, de sérum, de plasma ou dautres échantillons. Linvention permet la création de systèmes et de dispositifs de diagnostic qui permettent de passer de léchantillon à la réponse en toute transparence. Les dispositifs et les techniques décrits peuvent également réaliser lauto-assemblage assisté de molécules, de polymères, de nanocomposants et dentités mésométriques en structures tridimensionnelles ou dun ordre supérieur.
